Subject: [PATCH] fix(test): skip grpc-js resolver tests that use unavailable
 domain (#25039)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Summary

- Skip 2 tests that use `grpctest.kleinsch.com` (domain no longer
exists)
- Fix flaky "should not keep repeating failed resolutions" test

These tests were originally skipped when added in #14286, but were
accidentally un-skipped in #20051. This restores them to match upstream
grpc-node.

## To re-enable these tests in the future

Bun could set up its own DNS TXT record at `*.bun.sh`. According to the
[gRPC A2
spec](https://github.com/grpc/proposal/blob/master/A2-service-configs-in-dns.md):

**DNS Setup needed:**
1. A record: `grpctest.bun.sh` → any valid IP (e.g., `127.0.0.1`)
2. TXT record: `_grpc_config.grpctest.bun.sh` with value:
   ```

grpc_config=[{"serviceConfig":{"loadBalancingPolicy":"round_robin","methodConfig":[{"name":[{"service":"MyService","method":"Foo"}],"waitForReady":true}]}}]
   ```

Then update the tests to use `grpctest.bun.sh` instead.

## Test plan

- [x] `bun bd test test/js/third_party/grpc-js/test-resolver.test.ts`
passes (20 pass, 3 skip, 1 todo, 0 fail)
